Advent

Advent (from the Latin word adventus, meaning "coming") is a season of the Christian church, the period of expectant waiting and preparation for the celebration of the Nativity of Jesus, in other words, the period immediately before Christmas.

¹⁰Again the LORD spoke to Ahaz, ¹¹"Ask a sign of the LORD your God; let it be deep as Sheol or high as heaven." ¹²But Ahaz said, "I will not ask, and I will not put the LORD to the test." ¹³And he said, "Hear then, O house of David! Is it too little for you to weary men, that you weary my God also? ¹⁴Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. ¹⁵He shall eat curds and honey when he knows how to refuse the evil and choose the good. ¹⁶For before the boy knows how to refuse the evil and choose the good, the land whose two kings you dread will be deserted. ¹⁷The LORD will bring upon you and upon your people and upon your father’s house such days as have not come since the day that Ephraim departed from Judah—the king of Assyria." —Isaiah 7:10-17 ESV

Isaiah 14:9 (above) from the Latin Vulgate [emphasis added]:

infernus subter conturbatus est in occursum adventus tui suscitavit tibi gigantas omnes principes terrae surrexerunt de soliis suis omnes principes nationum

The Hebrew word from which the Latin is derrived for this verse is בוא bow' which means, "to go in, enter, come, go, come in.

Advent

Advent (from the Latin word adventus, meaning "coming") is a season of the Christian church, the period of expectant waiting and preparation for the celebration of the Nativity of Jesus, in other words, the period immediately before Christmas. It is the beginning of the Western Christian year and commences on Advent Sunday. The Eastern churches begin the liturgical year on 1 September. The Eastern Christian equivalent of Advent is called the Nativity Fast but it differs both in length and observances.

The progression of the season may be marked with an Advent calendar, a practice introduced by German Lutherans. At least in the Roman Catholic calendar, Advent starts on the fourth Sunday before December 25; in other words, the Sunday between November 27 and December 3 inclusive.

Latin adventus is the translation of the Greek word parousia, commonly used in reference to the Second Coming of Christ. Christians believe that the season of Advent serves a dual reminder of the original waiting that was done by the Hebrews for the birth of their Messiah as well as the waiting that Christians today endure as they await the second coming of Christ.
